Roberto Osuna was signed as an international free agent as a 16-year old in 2011, and just after his 20th birthday he made the Blue Jays 25-man roster out of spring training. Initially he was not the closer on the team as John Gibbons elected to try both Brett Cecil and Miguel Castro in that role to start the year. On June 22, Osuna came in for two innings, which was his first career save on five strikeouts. In August that season he pitched in 10 games and went 9 for 9 in save opportunities, and at one point saw his ERA drop to 1.
